vue实现根据多选框按钮，动态给百度地图添加和删除相应的覆盖物-白红宇

1.定义对象数组

cars:[ { indexName: 0, name:'登高车', state:false, icon:'static/img/mapMarker/car1.png', points:[ [116.316967,39.990748], [116.323938,39.989919], [116.31311,39.9890], [116.315,39.9890], ], }, { indexName:1, name:'高压灭火剂', state: false, icon:'static/img/mapMarker/car2.png', points:[ [116.328896,39.988039], [116.321135,39.987072], ]

},      {        indexName: 2,        name:'高压强磁堵漏装置',        state: false,        icon:'static/img/mapMarker/car3.png',        points:[          [116.332453,39.989007],          [116.324045,39.987984],        ]      },      {        indexName: 3,        name:'排烟车',        state: false,        icon:'static/img/mapMarker/car4.png',        points:[          [116.322085,39.974316],          [116.322108,39.986381]        ]      },      {        indexName:4,        name:'泡沫车',        state: false,        icon:'static/img/mapMarker/car5.png',        points:[          [116.332508,39.982311],          [116.332918,39.986386]        ]      },      {        indexName: 5,        name:'气动起重气垫',        state: false,        icon:'static/img/mapMarker/car6.png',        points:[          [116.329258,39.958318],          [116.329606,39.966381]        ]      },      {        indexName:6,        name:'移动供气源',        state: false,        icon:'static/img/mapMarker/car7.png',        points:[          [116.324208,39.988331],          [116.324667,39.986383]        ]      },      {        indexName:7,        name:'云梯车',        state: false,        icon:'static/img/mapMarker/car8.png',        points:[          [116.320258,39.988371],          [116.321618,39.986389]        ]      },    ],复制代码

2.data定义二维数组myOverlays:[]; 3. mounted(){ this.$nextTick(function () { this.initMap(); }); },

4.methods(){ initMap(){ this.createMap() ; //创建地图 }, createMap(){//创建地图 let map = new BMap.Map("map");//在百度地图容器中创建一个地图 let point = new BMap.Point(116.323066,39.989956);//定义一个中心点坐标 map.centerAndZoom(point,16);//设定地图的中心点和坐标并将地图显示在地图容器中 map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放 window.map = map;//将map变量存储在全局 }, addOverlays(n){//添加覆盖物 let _th = this.cars; let array=this.myOverlays; array[n]={ label:[], Icon: new BMap.Icon(_th[n].icon, new BMap.Size(30, 30), {offset: new BMap.Size(10, 25),}), markers:[] }; for (let j = 0; j < _th[n].points.length; j++){ let point = new BMap.Point(_th[n].points[j][0], _th[n].points[j][1]); array[n].markers[j]=new BMap.Marker(point, { icon: array[n].Icon }); array[n].label[j] = new BMap.Label(_th[n].name, {offset: new BMap.Size(-5, 30)}); array[n].label[j].setStyle({ color: '#fff', fontSize: '10px', padding: '5px', background: 'rgba(0, 0, 0, .5)', border: '1px solid #fff', fontFamily: "微软雅黑", borderRadius: '3px' }); array[n].markers[j].setLabel(array[n].label[j]); map.addOverlay(array[n].markers[j]); } }, clearOverlays(n){//删除覆盖物 let array=this.myOverlays; for (let i=0;i< array[n].markers.length;i++){ map.removeOverlay(array[n].markers[i]); } }, selectBox(car){//多选框按钮操作 car.state = !car.state; let carType = car.indexName; if(car.state==true){ this.addOverlays(carType); }else { this.clearOverlays(carType); } } }
